MODIS Daily Global BRDF Volumetric Parameter for Band 6

Daily global data provides the volumetric parameter for the Bidirectional Reflectance Distribution Function (BRDF) model for MODIS band 6. The dataset is produced by LPCLOUD using 16 days of Terra and Aqua MODIS observations, temporally weighted to the ninth day, at a 30 arc second (1,000 meter) resolution.

Use Cases

• Derive BRDF and albedo values for MODIS band 6 using the volumetric parameter alongside isotropic and geometric parameters.
• Assess daily land surface reflectance dynamics for climate modeling grids using the volumetric parameter layer.
• Filter for high-quality full inversion results in science applications using the band-specific quality flags.
• Integrate the volumetric parameter layer with other MCD43D files (MCD43D01 through MCD43D30) for comprehensive BRDF analysis across MODIS bands 1-7 and aggregated bands.

Strengths

• Daily temporal resolution supports analysis of short-term surface reflectance changes.
• Global spatial coverage at 30 arc second resolution suitable for climate simulation models.
• Data is produced using a 16-day observation window from two MODIS instruments (Terra and Aqua) for robust model inversion.

Limitations

• Each product file contains only one data layer, requiring multiple file downloads for full parameter analysis.
• Known issues exist, requiring users to consult external assessment websites for complete problem information.
• The large file size per single-layer product may complicate data management and processing workflows.
